Lamb's lettuce, also known as corn salad or lamb's lettuce, is a small salad green native to Europe and Western Asia. It grows wild in fields and wastelands before becoming a common vegetable in gardens. The term " Green Lamb 's Lettuce" refers to varieties with compact rosettes and tender green leaves, well-suited to late summer and autumn sowing in gardens with cooler climates.

Its low-growing rosettes easily weave their way between other crops, carpeting the ground with a perennial ground cover for the cooler months. Its modest and steady growth makes it an ideal companion for kitchen gardens that prioritize continuous harvests. Mild in flavor and cold-hardy, it consistently accompanies the cycle of the seasons, offering gardeners a comforting salad green as the days grow shorter.
